In Engelmann's classic experiment, why were the oxygen-requiring bacteria clustered around the regions of Spirogyra algae that were bathed in red, blue, and violet light?


▸
because photosynthesis is most active in those wavelengths of light and thus more oxygen is consumed by the algae in those regions


▸
because chlorophyll is green and thus reflects green light


▸
because photosynthesis is most active in those wavelengths of light and thus more oxygen is produced by the algae in those regions
